The Cheapest I can find is Pinnacle NOX2, And BSN Nitrix. Which of the two companies would you trust? I have never heard of BSN until a few weeks ago. Being from Canada my options are limited, I have tried several health food stores in my area and nobody carries it. I have to order it online from SND's canadian location. I even wanted to get my hands on some Andro, but as it turns out it is banned in Canada. Its Funny Andro is banned, but Ephedrine isn't. Because of the strict laws I will only order from a canadian retailer, with my luck I will spend a couple hundred on supplements and they will end up being held at the boarder and I never get them and I am out the money.
